What's a frugal trick you've chanced upon recently?
I accidentally semi-reinvented the "trencher". Basically, in medieval times, food would be served on a slab of bread and that would kinda be the plate. Or, you know, bread bowls for soup and the like.
I have an air fryer, and I've learned I can line the basket in a large flour tortilla, and it generally keeps whatever I'm cooking/warming up from getting the pan too dirty aside from some easily knocked-out crumbs.
I hate washing things, and I hate wasting paper liners, so it lets me cut down on those, and I can just eat the tortilla.
Talking about clothes....
I like to dress up a bit. More formal than others. So the opposite of fabric softener (I use 25% acidity white vinegar for that): potato starch for crisp shirts.
If you are courageous enough: yes, you can wash suit jackets. Cold, very little detergent, wool cycle, slow spinning. But jackets hardly need that anyway. A good brush gets you a long way. And a spray bottle of Vodka, to freshen up the lining every once in a while (no, you won't smell like a drunkard).
And of course: second hand clothes. Especially the more formal stuff because (way too) few people walk around in suit and tie and only buy them to wear once for some formal occasion and resell them afterwards for ridiculously cheap.
